13. The head 11 has two opposite bushing 1 15 anc as To all whom it may concern:

portions providing shoulders 1% Be it known that I, GEORGE T. STRITE, a

citizen of the United States, residing at clearly shown in Figs. 1 and 2. A. movable Minneapolis, in the county of Hennepin an semi-cylindrical bearing block 16 provided with a complementary bushing 17 in reference to the bushing 13 of bearing head 11, is provided with straps 18 and 19, said straps having inner faces adapted to engage flusi with corresponding faces extending at the sides of the bearing head 11, as most clearly shown in Fig. 2. Near the ends of the straps bosses 20 and 21 thicken the material of the same and through the center of said bosses are alining apertures 22 and 23 of elliptical shape, as most clearly shown in Fig. 3, each of said apertures having opening thereinto a short slot 24; extending through the thickness of the wall of the strap for a purpose later to be given. Across the insides of the straps 18 and 19 adjacent the aforesaid thickened portions are formed slots or keyways 25 and State of Minnesota, have invented certain new and useful Improvements in Connect ing-Rods, of which the following is a specification.

My invention relates to connecting rods, primarily to connecting rods extending from the crank shaft of engines.

The primary object of my invention is to provide a connecting rod for the above purpose in which the bearing is formed of a two-part member, one being relatively movable along the other in combination wit means for moving said members relatively to take up wear in the bushings without removing said bushings or taking off the connecting roc.

It is also an object of my invention in accomplishing this result to connect the rela- 26. These keyways provide top shoulders 27 tively movable part 0 the bearing to the and 28 and by reference to Fig. f it will be hich shall seen that the line of the shoulders on the connecting rod proper by means w engage directly between projections on said straps relative to the line of the shoulders on relatively movable member and on the rod the sides of head 11 are oblique. In the exand which itself shall be capable of a moveample shown in Fig. l the line of shoulder 27 is shown as parallel with the elements of the cylindrical bearing while the line of shoulder 15 is oblique thereto, but the same result obviously can be obtained by reversing this order or by having both of said lines obliquely disposed with respect to the elements of the bearing cylinder.

Adapted to seat in the slots 25 and 26 are key members 29 and 30 having their end walls obliquely-disposed at the same angles as the relative disposition of the walls of the shoulders on the rod head 11 and straps 18 and When these key members ment transverse to the direction of the rod to effect the aforesaid movement, in combination with means for moving the connecting means which shall not receive any of the shock or strain incident to the direct thrust of the connecting rod, because said operating means itself forms no part of the connection between the movable bearing member and the rod.

The full objects and advantages of my invention will appear in connection with the detailed description thereof and are particularly pointed out in the claims. 19, respectively.

In the drawings illustrating the applicaare positioned as indicated in Figs. 1 and 2 tion of my invention in one form -Figure 1 j the sides thereof engage the respective shoulders of the straps and rod head, thereby connecting the movable bearing member 16 to the rod head to complete the bearing. A bolt hole 81 extends transversely through the shank 10 in proper alinement with the oblong holes 22 and 23 in the straps when these straps are assembled. A bolt 32, as shown in Fig. 5, provided with a head 38, threaded end 3 1, screw slot 35 and wing teeth 36 and 37 extending outwardly from the sides thereof is inserted through the holes in the straps and said bolt hole. In order that the wing members 36 and 37 may pass through, the slots 24 are provided and a similar slot 3 extending from the bolt hole 31 to provide is an end view of the bearing head of a connecting rod embodying my invention. Fig. 2 is a similar view taken in section through the said head. Fig. 3 is a side view of the parts shown in Fig. 1 with the operating bolt shown in section. Fig. 1 is a transverse section through one of the adjusting connecting keys. Fig. 5 is a view of the bolt for operating the said keys. Fig. 6 is a partly sectional view of a combinationwrench for use in connection with my invention.

The shank 10 of the connecting rod is provided at its en with a bearing hea formed with a semi-cylindrical bearing cavity 12 in which is secured the usual half clearance, oblong holes 39 being formed in' the key members corresponding to the holes 22 and 23 in the straps but having their longer dimension rection, all as clearly shown in arrangement permits the bolt 32 to be assembled through the straps and the hole 31 in the shank head and the wing members 36 and 37 to be positioned in the holes 39 in the keys 29 and 30. As before stated these holes have the longer dimension thereof exding longitudinally or transversely to the shank of ing rod. The keys 29 and 30 therefore may have movement across said bolt 32 and since the keys are in engagement with the walls of the shoulders on the straps and on the shank head, respectively, and the key walls are relatively oblique, it follows that such a movement of the keys will have a wedging action to cause the bearing to move inward toward the bearing head 11. Each of the oblique openings and 30 is provided with tending from a V openings and adapted to receive the wings 36 and 37, respectively, on the bolt 32, as shown in Fig. 4. Upon the threaded end 34 of bolt 32 a nut 41 is turned by and nary strength operator applied to the cause a binding itself in any way directly support the movable bearing head 16, the

Washingto head at is transmitted keys 29 and 'I he bolt of course holds 1. -A connecting rod comprising a bearing head at the end thereof having plane faced outside Walls, a movable bearing cap provided with straps overlying and enga ing said faces, wedge keys having a bearing between the head and for connecting the bearing cap to the bear ing head, a bolt extending and rod for holding them transversely thereby to effect movement of the bearing cap.

2. A connecting rod comprising a bearing he end thereof, a movable bearing straps engaging the outof the bearing head, wedge keys having a bearing between the head and a portion of said str aps for connecting the bearing cap to the bearing head, a boltiexkeys transversely thereb ment of the bearing cap. e

connecting rod comprisin a bearing head at the end thereof, a mova le bearing cap provided with straps engaging the outside faces of the bearing head, having a bearing keys being formed with oblong apertures iaving a notch extending from one side thereof, a bolt extending through the straps, rod and said oblong apertures for holding the straps and wedge keys in fixed relation to the rod, and teeth on the bolt meshing in hes, whereby turning of the bolt will move effect movement of the bearing cap.

In testimony whereof I affix my signature in presence of two witnesses.
